A steel pipe roof structure is provided to prevent the separation of steel pipes by coupling steel pipes laterally with strong coupling strength. A steel pipe roof structure is formed in a unified structure by coupling many steel pipes(200) provided with horizontal grooves(204) and connection grooves between a pair of angles(206), and placing concrete or mortar in the steel pipes, wherein a plurality of supports(202) are installed to the inside of the horizontal groove at regular intervals not to get distorted by load such as soil pressure, and a T-shaped hook(300) composed of a horizontal member and a vertical member is installed between the angles and a C-shaped latch(302) is installed to the supports to couple adjacent steel pipes strongly in the lateral direction. |
